Millipeds (Arthropoda: Diplopoda) Of The Ark - La - Tex. Vi. New Geographic Distributional Records From Select Counties Of Arkansas, C. T. Mcallister, H. W. Robison, L. C. Thompson, M. B. Connior
Journal of the Arkansas Academy of Science
We continue to report, in the sixth of a series of papers, new geographic records for millipeds of the state, including noteworthy records for some taxa collected from Crowley’s Ridge in eastern Arkansas. This contribution documents 47 new co. records and includes records for 19 species within 9 families and 5 orders. More uncommon millipeds found included Okliulus carpenteri (Parajulidae), Eurymerodesmus newtonus (Eurymerodesmidae), Pseudopolydesmus minor (Polydesmidae) and undescribed species of Ethojulus (Parajulidae) and Nannaria (Xystodesmidae). Undoubtedly, additional records will be reported in the future as several gaps in the distribution of Arkansas millipeds remain.
Scarab Beetles (Coleoptera: Scarabaeidae) In The Dung Of Native Arkansas Mammals, J. B. Kelley, J. L. Hunt, M. B. Connior
Scarab Beetles (Coleoptera: Scarabaeidae) In The Dung Of Native Arkansas Mammals, J. B. Kelley, J. L. Hunt, M. B. Connior
Journal of the Arkansas Academy of Science
Dung beetles are important ecological components of natural ecosystems. One primary activity is the fragmentation and recycling of animal dung. Little is known about the ecological impact of beetles associated with the dung of mammals native to Arkansas. We surveyed the dung of native mammals within Arkansas to determine the species and distributional patterns associated with dung. We searched and collected beetles in situ from the dung or nests of native mammalian species within Arkansas. We also set simple pitfall traps using dung of various native Arkansas mammals as bait. Most of the beetles collected were common dung beetles. However, …

Effects Of Felled Shortleaf Pine (Pinus Echinata Mill.) Moisture Loss On Oviposition Preferences And Survival Of Sirex Nigricornis F. (Hymenoptera: Siricidae), Jessica Hartshorn
Effects Of Felled Shortleaf Pine (Pinus Echinata Mill.) Moisture Loss On Oviposition Preferences And Survival Of Sirex Nigricornis F. (Hymenoptera: Siricidae), Jessica Hartshorn
Graduate Theses and Dissertations
The European woodwasp, Sirex noctilio F. (Hymenoptera: Siricidae) utilizes pine as its host during larval development. Females drill through pine bark to deposit eggs, a symbiotic fungus, Amylostereum, and phytotoxic mucus into the tree. In their native range, these insects are not viewed as primary pests because they attack dead or dying trees. Over the last century, this woodwasp has been accidentally introduced into several countries in the southern hemisphere. Some regions have incurred millions of dollars in damage to large plantations of the widely planted pine species, radiata pine (Pinus radiata D. Don). Sirex noctilio was discovered …
The Biological Control Of Spotted Knapweed In The Southeastern United States, Carey R. Minteer
The Biological Control Of Spotted Knapweed In The Southeastern United States, Carey R. Minteer
Graduate Theses and Dissertations
Spotted knapweed is an invasive, short-term-perennial plant that is native to Eurasia. It was accidentally introduced into North America in the early 1890's and has since spread across The United States and Canada. Spotted knapweed degrades rangelands and pastures by negatively impacting native plants, increasing soil surface runoff and stream sediment yields, and reducing soil infiltration. A biological control program for spotted knapweed using Larinus minutus (Coleoptera: Curculionidae), was initiated in Arkansas in 2008. In this dissertation I described the releases of L. minutus and investigated the adult activity in the southeastern United States (Chapter 1), investigated the effects of …
Community Structure And Ecological Specialization In Plant-Ant Interactions, Paola Barriga
Community Structure And Ecological Specialization In Plant-Ant Interactions, Paola Barriga
Graduate Theses and Dissertations
Positive associations among species have contributed to the maintenance of biodiversity. These interactions are typically studied in pairwise fashion where two interacting organisms are the focus. This dissertation uses network theory to analyze positive plant-ant associations in three Neotropical forests. Obligate plant-ant mutualisms were used, where plants host the ants in domatia and provide food bodies while the ants protect the plants and can feed them. A network approach was used to depict all obligate plant-ant interactions within a community. The main questions asked at the community level were: 1) Do network structure and levels of specialization change geographically and, …
Effects Of Associated Subcortical Beetles On Oviposition Behavior And Early-Stage Survival Of Sirex Nigricornis F. (Hymenoptera: Siricidae), Ace J. Lynn-Miller
Effects Of Associated Subcortical Beetles On Oviposition Behavior And Early-Stage Survival Of Sirex Nigricornis F. (Hymenoptera: Siricidae), Ace J. Lynn-Miller
Graduate Theses and Dissertations
Sirex (Hymenoptera: Siricidae) woodwasps develop within xylem of host conifers. Sirex females drill through the bark, phloem and into xylem tissues where they deposit eggs along with a symbiotic Amylostereum fungus. The presence of Amylostereum is necessary for successful development of Sirex immatures as the larvae are unable to derive adequate nutrition from xylem in the absence of the fungus. The Eurasian woodwasp, Sirex noctilio F., was discovered in northeastern North America in 2004. Sirex noctilio has caused significant economic damage in Pinus radiata D. Don plantations of the southern hemisphere, but is of little economic significance in its native …
Flight Period And Species Composition Of Sirex (Hymenoptera: Siricidae) And Associated Deladenus (Nematoda: Neotylenchidae) Within Arkansas Pine Forests, Danielle Keeler
Flight Period And Species Composition Of Sirex (Hymenoptera: Siricidae) And Associated Deladenus (Nematoda: Neotylenchidae) Within Arkansas Pine Forests, Danielle Keeler
Graduate Theses and Dissertations
The European woodwasp, Sirex noctilio F. (Hymenoptera: Siricidae), which is a known destructive pest of pine in the southern hemisphere was recently discovered in the eastern United States. Before we can understand how S. noctilio may affect pine forests throughout the United States, we need a better understanding of native Sirex and the role they play in the ecosystem. The objectives of this research were to 1) determine species composition and flight period for native Sirex; 2) confirm presence of parasitic nematodes, Deladenus (Nematoda: Neotylenchidae), within adult Sirex; 3) investigate Deladenus parasitism rates; 4) verify the number of Deladenus species …
Early Season Population Dynamics And Residual Insecticide Effects On Bird Cherry-Oat Aphid, Rhopalosiphum Padi In Arkansas Winter Wheat, Beven Mcwilliams
Early Season Population Dynamics And Residual Insecticide Effects On Bird Cherry-Oat Aphid, Rhopalosiphum Padi In Arkansas Winter Wheat, Beven Mcwilliams
Graduate Theses and Dissertations
Bird cherry-oat aphid is a common pest of Arkansas winter wheat. This aphid vectors barley yellow dwarf virus which may cause extensive crop damage and yield loss when wheat is infested by virulent aphids in the fall. Some suggest this damage may be avoided using insecticide seed treatments if growers are unable to delay planting, as is recommended. Field population dynamics of bird cherry-oat aphid during fall 2009 and 2010 was assessed through random sampling of whole plants and pan trapping methods to evaluate aphid immigration. The field plots were divided into four subplots treated with a systemic insecticide seed …
The Role Of Ascorbic Acid In The Plant-Herbivore Interaction, Kelly Ann Carruthers
The Role Of Ascorbic Acid In The Plant-Herbivore Interaction, Kelly Ann Carruthers
Graduate Theses and Dissertations
Ascorbic acid (AsA), vitamin C, is an important molecule that is vital for both human and plant health, because it aids in the detoxification of reactive oxygen species (ROS) caused by various abiotic and biotic stresses including UV, salinity, ozone, and attack from pathogens In order to understand the role of AsA in the plant-herbivore interaction, we looked at the effects of the wound-responsive hormones, jasmonate, wounding, and herbivory on AsA content. Our study is the first to directly compare the effects of wounding and jasmonates on AsA levels in plants. We looked at the effects of wounding and methyl …

Population Structuring And Transmission Dynamics Of A Laboratory Colony Of Gromphadorholaelaps Schaeferi: A Symbiotic Mite Of The Madagascar Hissing Cockroach Gromphadorhina Portentosa, D. J. Richardson
Journal of the Arkansas Academy of Science
Gromphadorholaelaps schaeferi is a symbiotic mite associated with the Madagascar hissing cockroach Gromphdorhina portentosa. The population structuring of G. schaeferi is described based on examination of 19,421 mites collected from 1,915 individuals of G. portentosa taken from a large laboratory colony. The mites exhibited an overall prevalence of 50.7% and mean intensity (+SE) of 20.0 (+0.6) with an infestation intensity range of 1-116, and relative abundance (+SE) of 10.1 (+0.4). Both prevalence and mean intensity of infestation exhibited a dramatic increase with increasing cockroach size/age. By the time cockroaches reach 40 mm the prevalence is nearly 100%. Mean intensity increases …

Invertebrate Abundances And Diversity Of A Six Year Old Organic Apple Orchard In Northwest Arkansas, Cory Johnson, Brina Smith, Mary C. Savin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Ground cover mulch applications in perennial systems can have multiple benefits, one of which may be to enhance the size and diversity of the ground surface faunal community. To determine if ground cover and organic fertilizer applications altered invertebrate communities, litters in an experimental 0.4-ha organic apple orchard in Fayetteville, Ark. were sampled during a four week period beginning in February 2012. The orchard was planted in 2006 in a replicated 4 × 3 factorial design with organic ground cover and fertilizer treatments applied annually each April. Invertebrates were extracted using Berlese funnels and hand sorting techniques. Ground covers (wood …

Ozark Highland Cunaxidae (Acari: Prostigmata): Descriptions And Keys To Genera Found To Occur In The Region And A New Phylogenetic Hypothesis For The Family, Michael Joseph Skvarla
Ozark Highland Cunaxidae (Acari: Prostigmata): Descriptions And Keys To Genera Found To Occur In The Region And A New Phylogenetic Hypothesis For The Family, Michael Joseph Skvarla
Graduate Theses and Dissertations
Fourteen genera of Cunaxidae (Acari: Prostigmata) are reported from the Ozark Highlands for the first time. Descriptions, diagnoses, and illustrated keys to genera and world species are given. Five new species are described and illustrated and an additional 6 known species are recorded from the region. The first rigorous phylogenetic hypothesis for Cunaxidae is presented. Based on morphology, it suggests the current subfamilial classification scheme does not reflect the evolutionary history of the family. Unfortunately, bootstrap values and resolution are low, suggesting the need for further indepth molecular analyses.

Chemical Ecology, Population Dynamics And Insecticide Susceptibility Of Lesser Mealworm Alphitobius Diaperinus (Panzer) (Coleoptera: Tenebrionidae), Narinderpal Singh
Graduate Theses and Dissertations
The lesser mealworm, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), is a serious, cosmopolitan pest present in poultry production facilities, where it slows down weight gain in chicks, carries disease–causing organisms, and causes damage to poultry insulation. The first study estimated that the lesser mealworm densities in poultry litter applied to pastures were 3.5, 2.2 and 0.4 million larvae, adults and pupae, respectively, per hectare in Savoy, Arkansas. The repercussions of these adult beetles are that they often disperse to and reinfest poultry houses with the potential to vector disease to poultry, and disperse to invade human dwellings resulting in litigation. The …
